Announcing the Datadog Terraform provider v4.0.0

The release of Datadog Terraform provider v4.0.0 introduces significant enhancements aimed at improving reliability, security, and governance for managing Datadog configurations as code. This major update offers predictable monitor governance, allowing permissions to persist as defined in configurations, and introduces a unified AWS integration resource to streamline management by replacing four separate legacy resources. The new version also emphasizes credential security by tightening application key workflows, removing the datadog_application_key data source, and ensuring compatibility with one-time read application keys. It further upgrades to support Terraform protocol v6, enabling more efficient future improvements to schemas and validation. As teams prepare to upgrade, they are encouraged to verify their Terraform CLI version and follow migration guidance, with the option to continue using older configurations if they choose to remain on v3.
